Create a PST file and put a contact folder inside of it with all the contacts you want. Then select File > Import / Export and export the contacts as an Excel file. Then e-mail that file to the users and have them do an IMPORT from the excel file into their contact list.

Another option is to select all the contacts and drag and drop them into an e-mail. Then the user can add them by opening them on the blackberry or opening them on the PC and selecting "Save and close" on each contact.
